AP Calculus AB Practice Set 4

The population of a city grows at the rate of P\prime(t) people per year. If there are 500,000 people in the city at time t = 0, which of the following expressions gives the population of the city at time t = 5 years?

Consider a function h that is continuous on the closed interval [0,3] with h(0) = 2 and h(3) = 6. Of the following conditions, which would guarantee that there is a number d in the open interval (0, 3) where h\prime(d)=2 ?

p"(x)=x(x+3)^2(x-5)^3
q"(x)=x(x+3)^2(x-5)^3+2
r"(x)=x(x+3)^2(x-5)^3-2

Consider a different set of values for a function g(x) at selected values of x. If g(x) is twice-differentiable on the interval 1\le x\le5 , which of the following statements could be true?

Consider a defined function p\left(x\right)=\ln{(2+x^2)} , and another defined function q\left(x\right)=x^7+x^4 . The line tangent to the graph of p at x = 2 is parallel to the line tangent to the graph of g at x = b, where b is a positive constant. What is the value of b?
